ARK-499-503: ExecutionProof Enterprise Adapter Series + Synthetic-Year Endurance Simulation

ARK-499 through ARK-503: Enterprise Adapter & Operational-Readiness Series This testbed demonstrates ExecutionProof enforcement across real enterprise boundaries (PostgreSQL 17, git CI/CD, self-hosted OIDC/IAM) plus bounded operational-continuity smoke and synthetic 1-year endurance simulation. Results Summary: ARK-499 (PostgreSQL 17 transaction boundary): EXPERIMENT-PASS, 7/7 arms, 0 leaks ARK-500 (git CI/CD release boundary): EXPERIMENT-PASS, 7/7 arms, 0 leaks ARK-501 (self-hosted RS256 OIDC/IAM): EXPERIMENT-PASS, 7/7 arms, 0 leaks ARK-502 (operational continuity): SMOKE-PASS (bounded smoke: 418 ops, 132 commits, 0 leaks; ≥14-day endurance NOT-EXECUTED); SYNTHETIC-YEAR-PASS (365 simulated days, ~13K ops, 12 restarts, 0 chain breaks, 0 leaks — logic-tested, NOT wall-clock endurance) ARK-503 (independent review package): NOT-EXECUTED, awaiting human reviewer (0 scored PASS) Scored contribution: 21 case records, all PASS (ARK-499/500/501 only) Chain integrity: 428-record continuous hash chain, 0 linkage breaks, independent verification confirmed Honest Labels (mandatory): Real but self-hosted (NOT Docker/K8s/cloud orchestration, NOT Okta/AzureAD/Auth0) ARK-502 smoke = bounded (NOT ≥14-day continuous endurance) ARK-502 synthetic-year = SYNTHETIC (logic-tested, NOT wall-clock endurance) ARK-503 = packaged (NOT independently reviewed/scored) Tamper-evident (NOT cryptographically unforgeable without key compromise) Engineering evidence (NOT formal certification or audit) Contents: Full testbed source code (frozen gate/guards/proofstore + new adapters) 428 ProofRecord chain (all experiments) 21 scored case results + experimental report ARK-503 independent review package (frozen, awaiting reviewer) Synthetic-year simulation (demo + real mode) Preregistration v1.0 (SHA-256 verified before execution) Reproduce: pip install -r requirements.txt && python3 run_all.py Related: Part of the ExecutionProof public evidence corpus.
